[PATCH v2 0/2] phy: rockchip: inno-hdmi: Change TMDS rate handling to configure() ops

[Jonas Karlman]

This series adds support for using phy_validate() and phy_configure()
with this HDMI PHY as an alternative to current in-tree unused way of
using PHY bus width to configure the TMDS character rate.

The only known users that calls phy_set_bus_width() on this PHY are my
out-of-tree HDMI 2.0 patches for Rockchip RK3228/RK3328, i.e. those
originating from LibreELEC (also carried by other distros), the
downstream vendor kernel uses a different implementation that also calls
phy_set_bus_width() on this PHY.

Patches that calls phy_validate() and phy_configure() on this PHY should
land on mailing lists any day now.

This series is part of a larger multi series effort to:
- phy: rockchip: inno-hdmi: Change TMDS rate handling to configure() ops
- drm/rockchip: dw_hdmi: Misc cleanup and propagate bus format
- drm: bridge: dw_hdmi: Misc enable/disable, CEC and EDID cleanup
- drm/bridge: dw-hdmi: Improve input/output bus format handling
- drm/bridge: dw-hdmi: Convert to a HDMI bridge and use of bridge connector
- drm/bridge: dw-hdmi: Add and use tmds_char_rate_valid() plat data ops
- drm/meson: hdmi: Misc cleanup and use CEC notifier helpers
- drm/rockchip: dw_hdmi: Enable YCbCr and Deep Color modes

Changes in v2:
- Split into two patches, one that adds new ops and a second that remove
  the old and unused workaround
- Add validate() ops to validate that the TMDS rate is supported
